A group of hackers that goes online with the name Ghost Squad Hackers has defaced for the second time in a week a site of the European Space Agency (ESA) The group claims to have hacked numerous organizations and government agencies over the years, including US military, European Union, Washington DC, Israeli Defense Forces, the Indian Government, and some central banks. The ESA experts have yet to fix the problem, they only removed the installation of the CMS/web application, the team appears to be focused primarily on operations against governmental agencies.”]
